If your macro definitions aren't too weird you can try the trace.tmac
file to improve debugging:

  groff -ww -Tps -m trace -m meta foo > foo.ps 2> foo.log

To really help you here I need a simple example of what you want to
do.  I don't have the time to analyze your macro package, sorry.

Again I need a simple sample.

grohtml is still under construction; right now Gaius is working on a
new set of patches to improve tables.  Since the CVS is down
currently, I can't apply patches.  Please download the current
development version of groff a few days and test your macros.  It is
easily possible that you find new bugs...
